Calc

Baby Formula Calc is an iOS app founded by pediatric gastroenterologist Dr. Diaz-Calderon. It works out formula preparations in seconds, a calculation that used to take 10 to 15 minutes of a consult.

Two calculators, one promise: the right amount of formula every time, shown clearly enough that a parent trusts the number.
